Critical doses determined using two different metrics for lysozyme 7.2 mg ml−1 in the presence and absence of different additives to limit radiation damage. White columns: critical dose defined as the dose where the increase in Rg is maximum 10%. Black columns: critical dose specified as the dose required to change Rg by a maximum of 0.1 nm relative to the initial data frame, as defined by Jeffries et al. (2015). All samples were measured in static mode (DTT: dithiothreitol; Asc: ascorbic acid; Glyc: glycerol; U: uridine). |
